OF NEV YORK, N. Y.

PORTABLE WOODN BOOTH.

SPECIFICATION forming part of Letters Patent N o. 469,017, dated February 16, 1892.

Application filed July 23, 1891. Serial No. 400,407. (No model.) Y

To all whom t may concern.- Be it known that I, CHARLES FRED Hons- DON, a citizen of the United States, residing in the city and State of New York, have invented anew and useful Improvement in Portable Wooden Booths, of which the fol- My present invention is an`improvementupon the device of Letters Patent N o. 442,97 9, issued to me as assignee of- H. A. Isberg De-v cember 16, 1890, and upon the device of my patent, No. 456,307, dated July 21, 1891; and

vide a portable wooden booth or house for telephonie purposes, which,while portable and folding to facilitate moving about, shall be sound-proof.

In carrying out my invention I employ two sets of hinged folding sections to form the inner and outer walls of the booth, the inner wall of sections being slightly smaller than the outer wall, so that a dead-air space is formed between the walls that will be a nonconductor of sound. These wall-sections rest upon a door of heavy boards, in which grooves are made to receive their lower edges and removable roofs or covers having grooved under sufaces are employed on each wall of sections, the one smaller than and Within the other, so that the deadair space is complete between said walls and covers.l Each wall of sections has a door and the doors are adja- The respective ends of the sections are in two parts hinged together to fold inwardly toward each otheryand theV respective fronts and backs \of\the sections are single parts hinged at their vertical edges to the end sections.

My improved booth or house can be taken apart for removal or storage in a few moments and as quickly set up again, as the respective parts are not necessarily connected together by screws or nails.

My improved booth is preferably longer than wide.

In the drawings, Figure 1 is an elevation of my improved booth. Fig. 2 is a vertical crosssection of the same, and Fig. .8 is a sectional The outer wall or set of hinged folding sections is composed of the front a, back b,

are preferably made of framepieces with panels of narrow tongue and grooved wood strips or cloth. The front and back are hinged 5 5 at their vertical edges to rthe ends, and the two parts composing the ends are hinged together to fold inwardly. The-inner wall or set of hinged folded sections is composed of the front e, back f, and two-part ends h h and 6o i i', and doors 7c Z are provided and hinged, as shown, in the respective walls. The parts just mentioned are constructed and fold as .do the similar parts shown and described'in the patent herein referred to, and the same do not require further description. The doors k Z are made of tongue and grooved strips, with battens on the back, and said doors t within and between the top and bottom and vertical frame-pieces forming the front and 7o are hinged thereto. v

m represents thebottom or floor of the booth, which may be of heavy planks securely connected edge to edge. In this floor near the edges are parallel grooves n n about two inches apart, more or less, and of a size coinciding with the lower edges of the walls when distended and set up for use. The bottom edges of these walls are received in these grooves n n', and the upper edges of said walls '8o are received in grooves 4 6 in theunder face of the covers o o'. Y The inner wall is lower than the outer wall, so that a space of about two inches is maintained between the respective covers when in place, the same as between the walls, which forms a dead-air space, so that sound within does not pass out, and when the booth is employed for telephonie communication the occupant using the instrument inside does not disturb parties outside and 9o the talking is not overheard.

The complete booth is set up, preferably, by rst putting the outer wall in place on the floor or bottom. The inner wall is then carried in its folded condition within the outer wall and extended and put in place. The top or cover is now put on the inner wall and afterward on the outer wall to make the booth complete. The booth is taken'down for removal or storage by reversing this order of roo action.

I claim as my 'invention- Y l. A portable wooden booth composed of an outer and a smaller inner wall made up of hinged folding sections, a bottom or-iioor to receive and support the same, and separate tops or covers to the respective walls, whereby a complete dead-air space is formed around and above the inner Wall, for the purposes and substantially as set forth.

2. The combination, with the two sets of hinged folding sections forming the outer and inner Walls, of the bottom or floor having two parallel grooves to receive said Walls, and the covers vor tops 0 0', having grooved under surfaces to set upon the said Walls, whereby a dead-air space is formed all around, substantially as set forth.
